After the load of the differential anti fall device is released, it can immediately return to normal working condition

Time:2024-10-15 09:13:14 Click:197

The speed differential anti fall device can present two working states: one is the semi tense state when the human body can move freely while wearing the anti fall device, and the other is the tense state when the load of the anti fall device increases after a high-altitude falling accident occurs, and the ratchet and pawl lock the steel wire rope to prevent the human body from descending the system.

Compared with safety ropes, the internal structure of the speed difference anti fall device is slightly more complex, but its advantages are more obvious because the anti fall device has a certain braking distance during the process of human body falling, which can buffer a large amount of impact energy, so as not to cause sudden harm to the human body. When the human body returns to the safe zone, the load of the anti fall device can be immediately restored to normal operation state after the load is released.

When the human body transitions from suspension to a safe zone, the load weight of the speed difference anti fall device will also change. From the locking of the steel wire rope to the free entry and exit of the steel wire rope, the main contribution is due to the retraction function of the anti fall device's steel wire rope. The device responsible for retrieving the steel wire rope is the coil spring, which can act on the double pawl to retract it. Once the steel wire rope disengages from the teeth on the ratchet, it will resume normal operation.
